Question

我尝试使用来自JSON的数据在AngularJS中创建动态表单。我有这个工作：

HTML

    <p ng-repeat="field in formFields">
            <input 
                dynamic-name="field.name"
                type="{{ field.type }}"
                placeholder="{{ field.name }}"
                ng-model="field.value"
                required
            >
            <span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.required">Required!</span>
            <span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.email">Not email!</span>
    </p>
    <button ng-disabled="myForm.$invalid">Submit</button>                 
</form>

JS

angular.module('angularTestingApp').controller('DynamicFormCtrl', function ($scope) {

$scope.formFields = [
    {
        name: 'firstName',
        type: 'text'
    },
    {
        name: 'email',
        type: 'email'
    },
    {
        name: 'password',
        type: 'password'
    },
    {
        name: 'secondName',
        type: 'text'
    }
];}).directive("dynamicName",function($compile){
return {
    restrict:"A",
    terminal:true,
    priority:1000,
    link:function(scope,element,attrs){
        element.attr('name', scope.$eval(attrs.dynamicName));
        element.removeAttr("dynamic-name");
        $compile(element)(scope);
    }
}});

此代码有效，但问题是我不知道如何添加动态复选框或核对清单以及如何在表单中验证，如下所示：< / p>

angular.module('angularTestingApp')

.controller（＆＃39; DynamicFormCtrl＆＃39;，function（$ scope）{

$scope.formFields = [
    {
        name: 'firstName',
        type: 'text'
    },
    {
        name: 'email',
        type: 'email'
    },
    {
        name: 'password',
        type: 'password'
    },
    {
        name: 'city',
        type: 'checkbox',
        choices: [
            { name: "red" },
            { name: "blue" },
            { name: "green" },
        ]
    }
];})

提前感谢您的关注。最诚挚的问候！

您可以使用ngIf来了解是否应显示复选框或文本输入，如下所示：

<p ng-repeat="field in formFields">
        <input 
            ng-if="field.type != 'checkbox'"
            dynamic-name="field.name"
            type="{{ field.type }}"
            placeholder="{{ field.name }}"
            ng-model="field.value"
            required
        >
        <input
            ng-if="field.type == 'checkbox'"
            ng-repeat="choice in choices"
            type="checkbox"
            dynamic-name="field.name"
            ng-value="choice.name"
        >
        <span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.required">Required!</span>
        <span ng-show="myForm.{{field.name}}.$dirty && myForm.{{field.name}}.$error.email">Not email!</span>
</p>
<button ng-disabled="myForm.$invalid">Submit</button>

使用http://angular-formly.com/#/如何使它不适合您对JSON模型生成的html表单的需求，并且可以自定义方式提交所有文件？
